Fix: Backwards Compatibility Issue in stripe-python

### Describe the bug We have noticed a strange bug that when upgrading from v7 -> v8. StripeError -> http_body becomes None instead of valid dictionary ### To Reproduce Fill STRIPE_GB_SECRET_KEY with valid test/dev key and run the script. You will see that `http_body` is None, while `json_body` is valid dict. This is starting from v8. Before v8 both http_body and json_body contain identical data. ```python import stripe import os from dotenv import load_dotenv import shortuuid import json # Load environment variables from .env file load_dotenv() # Configure Stripe with your test API key stripe.api_key = os.getenv('STRIPE_GB_SECRET_KEY') def test_stripe_charge(): # Test parameters metadata = {} metadata['moto_charge'] = False params = { "amount": 2000, # $20.00 in cents "currency": "USD", "customer": "cus_xxx", # Replace with a test customer ID "description": "Test charge from script", "idempotency_key": shortuuid.uuid(), "metadata": metadata } try: print("Attempting to create charge...") stripe_charge = stripe.Charge.create(**params) print("Charge successful!") print(f"Charge ID: {stripe_charge.id}") print(f"Amount: ${stripe_charge.amount/100}") print(f"Status: {stripe_charge.status}") return stripe_charge except stripe.error.InvalidRequestError as e: # Invalid parameters were supplied to Stripe's API print(f"Invalid Request Error: {str(e)}") print(f"Invalid Request Error: {str(e.http_body)}") print(f"Invalid Request Error: {str(e.json_body)}") print(json.dumps(e.json_body, indent=2)) if __name__ == "__main__": test_stripe_charge() ``` ### Expected behavior Suddenly http_body instead of giving dict starts giving None. I think this is backward compatibility issue. ### Code snippets _No response_ ### OS macOS ### Language version 3.8 ### Library version stripe-python v8.0.0 ### API version Not sure ### Additional context _No response_
